This year alone has seen the launch of a three-course pizza in New York, chocolate-covered fries in Japan and a hash brown crust pizza in New Zealand. We look at other unusual and extreme fast food items you can buy around the world.

Meet the pizza, within a pizza, within a pizza. Sold at Krave It in Queens, New York, this is said to be the first-ever three-course pizza. It's designed to be eaten from the inside out, with fries and onion rings to start, cheeseburger sliders as the second course, and fried Oreos as the final dessert slice. Are you brave enough to eat it all?

Yes, your prayers have been answered, this is a pizza with a fried chicken base! KFC revealed the “all chicken, no crust” pizza is made from “100% chicken fillet, 100% mozzarella cheese and sauce made from California tomatoes”. The crispy base is then topped with pineapple, cheese sauce and even more chicken. Pinch us.

When there’s curly fries up for grabs, it’d be rude not to order them, right? The spicy coated fries may look delicious, but there’s a catch. Unfortunately, these twisted fries were available in Japan for a limited time only.

Our dessert dreams have been answered! You can now buy giant buckets filled with delicious soft-serve McFlurry ice cream. It comes with four empty cups and spoons to share with friends and make it a party. But you’ll need to live in France unfortunately…

An Oreo McFlurry is a go-to treat for many dessert fans, and McDonald’s knows that. So there’s now an Oreo menu available in Hong Kong. There’s an Oreo Chocolate cheese Tart, an Oreo Tiramisu and an Oreoccino... yes a cappuccino and Oreo cookie mash-up.

There have been sweet and savory combinations before but nothing quite compares to the pairing of melted white and milk chocolate drizzled over hot, salty fries. This treat may be one for the future, as production ended in February.

A breakfast treat around the world, the hash brown was reimagined as a pizza topping in New Zealand in 2016, encircling your favorite pizza with pillowy potato bites.

Over in Taiwan in 2012, McDonald’s made a combo of monochrome buns for its customers. While the black burger consisted of an ink-colored bun, two beef patties, mashed potatoes and truffle sauce, the white burger was filled with a fried chicken patty, bacon, mashed potatoes and mushroom sauce. Hardly your average order!

Stuffed pizza crusts have developed massively over the years, from cheese to hot dogs to even mini burgers encircling the pizza. Hong Kong's interpretation in 2014 took it a whole step further with caviar. Fancy!

Sounding more like a ravioli filling, in Italy in 2013 you found chicken replaced with spinach and Parmesan in McDonald’s nuggets. Although strange, it actually sounds reasonably tempting…

Can’t decide what to have for dinner? Opt for the Boloroni pizza that not only has a pizza base and double cheese topping but a sneaky layer of bolognese-flavored macaroni underneath.

Most McDonald’s fans will be familiar with the Fillet-o-Fish. In Japan this is given a twist by replacing the fish patty with one made of shrimp. Smothered in spicy sauce and topped off with a Big Mac bun, it’s an unusual twist on the classic.

Taco Bell has a range of ‘sweet’ treats. While some simply have a layer of chocolate within them, the Chocodilla in 2012 went one step further by having a Baby Ruth chocolate bar filling with peanuts, caramel and chocolate-flavored nougat. Unusual but seriously tempting.

If you’re usually a fan of cheeseburgers, this could be for you as it’s simply a wrap stuffed with battered paneer cheese, fresh veggies, seasoning and creamy sauce. This is a huge hit in India where paneer is an incredibly popular delicacy.

A combination of cuisines, this dish pairs a piece of fried chicken with a portion of spaghetti. A tricky meal to eat perhaps.

Breakfast was taken up a notch at Taco Bell when it introduced its Waffle Taco (now named the Breakfast Roll) in 2014. Containing both eggs and meat, it’s received a controversial reception but the company’s president concluded that he would rather people have an opinion than no opinion at all.

A traditional flavor combo in China was transferred into donut form at Dunkin’ Donuts in 2014. Topped with dried and dehydrated pork shavings, as well as pieces of seaweed, this is not for those with a sweet tooth.

Providing regional twists across the world, McDonald’s developed the McArabia for its Middle Eastern customers. Containing two chicken patties, salad and garlic sauce, all wrapped up in Arabic bread, it looks a delicious regional option.

Taking the traditional bratwurst and adapting it for its menu, McDonald’s released the limited edition Nürnburger, with three sausages in a bun topped with mustard. Despite Germans consuming 2.7 kilos of sausages each year on average, the burger got mixed reviews, mostly down to the fact the sausages were fried not grilled.

When you think of expensive gourmet burgers, Wendy’s is perhaps not the first place to spring to mind but the third biggest US fast food chain decided adding foie gras was worth it. As part of a $200 million (£153m) revival of the brand in Japan, it will be offered in 100 outlets, starting with the restaurant in the luxury shopping district of Omotesando.

The Netherlands is a long way from Mexico, but it’s where Burger King opted to introduce its Nacho Whopper in 2010. It contained the usual whopper patty stacked with nacho chips, jalapenos and ‘mexican sauce’.

For just $20, anyone looking to make their Prom extra special could order this extra special, finger lickin’ good corsage. Though sadly a limited edition item, it’s something you could easily recreate – if for any crazy reason you fancied wearing a piece of fried chicken on your arm for an evening.

An Asian breakfast staple, Congee is savory porridge, often flavored with meat, spring onions and crispy shallots. KFC offer its take as part of its breakfast alongside classics such as pancakes, waffles, breakfast rolls and traditional English scones.

Inspired by Heston Blumenthal’s food trickery, Krispy Kreme launched the Krispy Slider and Glazed Dog. While both sweet, they trick you into thinking they are 'normal' fast food items by mimicking the common ingredients. For example, when you tuck into the 'burger' you will actually being eating a chocolate mudcake topped with sweet cream ‘special sauce’ in a fluffy donut bun topped with sugar crystal ‘seeds’.

Cheese sandwiches are a well-known comfort food in Britain, as is yeast extract Marmite (the UK version of the Australian Vegemite). So Starbucks decided to slather Marmite in its cheese sandwiches in the UK. As its advertising slogan says, you either love it or you hate it.

Possibly ruining the sight of a burger forever, the Kuro Burger came on the scene in 2012 and again in 2014. ‘Kuro’, meaning black, is colored by the buns being smoked over bamboo charcoal and adding squid ink to both the cheese and ketchup. It looks unappetizing in the adverts, and reviews claim it wasn't a great taste in real life too.
